One end icvers 12 has a pivotal sliding engagement "with the slotted end of the arm 9 by iliczms of pin 01 Stud 1%. The opposite ends of the lovers are provided with slots 15 and arc adapted to lie in the forked end of a bracket Miami to be sliding'iy pivoted to said bracket by means of a pin or bolt 17. The bracket lfi is fixed. to a vertically-reciprocating bar 18,

which is slidingly mounted in guide-brackets 19 on the sides of the shaft-framework.

2O denotes an angularly-bent arm pivoted to the bar 18 and carrying at its outer end a roller 21, which is adapted to engage a guideway or track 22, fixed to the shaft-framework. The upper end of the' guideway or track 22 is curved inwardly towardthe side of the shaft and away from the side of the car.

23 denotes a pin or rod which projects laterally from the arm 20 and is in position to be engaged by a bracket-plate 2d, projecting from the side of the car, said pin or red forming the shaft or axle of the roller 21.

25 denotes a plate or bracket fixed to a block 25", slidably mounted in a slot 18*, formed in the lower end of the bar 18. 25" is arranged in the slot 18", having one of its ends connected to the upper wall of said slot and the other end connected to the upper end of the block 25*. 25 is located at thebase of the shaft 1 and projects into the path of downward movement of the bracket 24 on the car, and as the car approaches the limit of its downward movement the same will be brought into engagement with the plate or bracket 25 and actuate the bar 18, the spring 25 serving as a buffer to relieve the sudden jar of the car when the bracket thereon engages the bracket 25 on the bar 18.

A spring 18" is arranged between a projection on the bar 18 and one of the cross-pieces 3 of the su 'iporting-t'ramework and serves as a buffer for timber 18 torelieve the ear ofjar when the projection on the same engages the pin 23 on the arm 24,, which is connected to' the bar 18.

The doors 5 may be arranged at any level in the shaft, but are preferably near the upper end, while the operating mechanism is at the lower end of the same.

The operation is as follows: Assuming that the car is at the bottom of the shaft and the doors closed, as the car' ascends the plate 24 on the car will-"be brought into engagement with thelaterally-projecting pin or rod 23 on the arm 20, raising said arm and the bar 18 until the roller 21, carried by the arm 20, runs into the curved upper end of the track or guideway 22, which will disengage the rod 23 from the plate 24: and allow the car to pass on up the shaft. iThe upward movement of the bar 18, as just described, will cause the bolt 17 in the bracket 16, carried by the upper portion of the bar, toforce the inner ends of the levers. 12 upwardly and the outer ends of the same downwardly, which will cause the doors 5 to be opened by reason of the slotted and'pivc al connection of this end of the levers with 'the crank-arms 9 of the door-sections. The-parts remain in the position they are now A coiled spring The plate or bracket in until the car descends, which'when it 1.

reaches the lower end of theshaift will engage the plate 25 and draw the bar 18 downwardly, which will causea reverse action of the operating mechanism and clese the doors, as will be understood.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood withontreqnin ing a more extended. explanation.
